Anchors sample bug - stuck after lots of clicks

[De-Panther]

What happens:
Generating lots of anchors by clicking on screen.
After some clicks, the 3D scene is gone and I see only the camera input.
Click back allows me to return to flat screen, and clicking "Enter VR"(should change to AR?) the AR experience works again.

Expected:
Anchors will stop at a limit? going over the limit would delete old anchors?

Device: Samsung Galaxy S10e
Browser: Chrome 90

Looking at the source, there's MAX_ANCHORED_OBJECTS = 30, but I guess the device anchors limit is lower?

Regarding the "Enter VR", seems like the button text is set before isSessionSupported.
